Cancer is often found when someone starts to feel symptoms—pain, an abnormal growth, or maybe just fatigue. Now scientists have developed a computer program that could identify and locate cancer even before symptoms arise, opening the door for earlier screening and better treatment. The program, called Cancer Locator, detects tumor DNA in patient blood samples, and precisely pinpoints where the tumor is located in the body. In a small pilot study, it successfully diagnosed liver, lung, and breast cancer in 80 percent of cases, giving researchers hope that the program could eventually be used as part of regular health checks, eliminating the need for invasive biopsies.
